STEVAL-IPM30B

Hello.

Can this module work in configuration as typical H bridge with controlling only 2 phases for brushed dc motor? Trigerring signals for third phase would be grounded.

I see that recomended input voltage is from 125V - 400 V DC. Can this modul operate from 24V DC?

I think It's possible with custom firmware but MC Workbench doesn't support this type of control. However, there is an option called MTPA in the "Additional Features", which causes a phase shift for better performance of motors with the trapezoidal shape of BEMF (BLDC motors).

I will make a test whether it is possible to power the module from the source of a lower voltage than 125V. I will let you know.

Thank you very much for reply.

It was long time ago, I tested it with custom firmware.

I didn’t try to use it like H bridge, I used it for 3 phase inductuon motor.

Some simple scalar control with with sine table.

I remember bridge worked for 85V dc and 60V dc and not sure but think it was working also for 30V dc.

Good news. I want to test IPM board on small motors first. I want to control PMSM motors. Do you have some guide how to make scalar-based motor control? Did you use speed sensors?
